LIQUID-FUEL BURNER.

Specification of Letters Patent.

Patented Nov. 29, 1910.

T 0 all whom it may concern:

Be it known that we, JAMES C. MOQUERRY and Anon L. EVRETT, citizens of the United States, residing at North Fort-worth, in the county of Tarrant and State of Texas, have invented a new and useful Liquid Fuel Burner, of which the following is a specification.

This invention relates to liquid fuel burners designed more particularly for utilizing crude oils, and it is the object of the invention to provide a burner of this kind which is simple in construction, and highly efficientin operation.

The invention also has for its object to provide a novel form of retort or vaporizing chamber which permits the attachment of a plurality of burner nozzles.

With these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which,

I Figure 1 is an elevation of the burner. Fig. 2 is a plan view. Fig. 3 is a longitudinal section on the line 3--3 of Fig. 2.

In the drawing 5 denotes the retort or vaporizing chamber of the burner. This chamber is in the form of a cross, to one of the branches 6 of which the oil supply pipe 7 is connected, said pipe running to a reservoir 8 containing a supply of oil, and said reservoir being suitably elevated to provide a gravity feed. To the top of the reservoir is applied a strainer 9, and a cover 10, the latter fitting loosely on the reservoir to afford an escape for any pressure which may accumulate therein.

In the pipe 7 is a suitable valve 11 for controlling the flow of oil to the burner and between this valve and the reservoir a check valve 12 is connected to the pipe to prevent a return of pressure to the reservoir.

To the branch 13 of the retort chamber 5 which is opposite the branch 6 is connected an elbow 14, the outer end of which is upwardly presented. This elbow forms one of the burner nozzles. To the other branches 15 of the retort chamber are connected horizontally extending pipes 16 to the outer ends of which are attached cross couplings 17, the pipes screwing into one of the branches of the couplings. To the other branches of the couplings are connected elbows 18, the outer ends of which are also upwardly presented in the same manner as the elbow 14:, and also serving as burner nozzles. The several elbows forming the burner nozzles are flared in the direction of their discharge ends.

The nozzle 14, and the pipes 7 and 16 are connected to the retort chamber by reducers 19.

I11 the retort chamber 5 will be placed a supply of absorbent material as indicated at 20 in Fig. 3. This material may be asbestos.

Inasmuch as the burner nozzles are located in close proximity to the retort chamber 5, the latter is highly heated, and the oil is vaporized and issues in this form from the burner nozzles. The absorbent material 20 serves as a wick, and spreads the oil through the retort chamber, so that vapoi ization is facilitated.

A burner constructed as herein described is highly eflicient in operation, and it can be readily applied to any ordinary stove. It will be mounted in the fire box of the stove, the oil supply pipe 7 entering the same through an opening made in the stove wall at any convenient point. The draft will be regulated by the ordinary damper of the stove. By providing a plurality of burner nozzles, and by arranging them as shown, a large fire is had, and the flames are spread throughout the fire box so that the stove will be rapidly heated. If desired the number of burner nozzles. may be reduced by removing any of them, and stopping up the parts to which they are connected by a plug or any other suitable means.

What is claimed is A liquid fuel burner comprising a cruciform retort chamber, a fuel supply pipe connected to one of the branches of the chamber, a burner nozzle connected to the branch which is opposite the last mentioned branch and located in close proximity to the retort as our own, We have hereto afiixed our signachamber to heat the same, pipes connected tures in the presence of two Witnesses.

to the other branches of the chamber and eX- JAMES ORAVENS MOQUERRY tending outwardly 'therefrom'horizontlly cross couplings mounted on the outer ends ARCH LETROBE EVRETT' of the pipes, and burner nozzles connected to V lVitnesses: the branches of the couplings. C. NUMBER,
